barcode --> "edocrab"
The last one I used though ..had to run in the back ground 24-7 and huge memory foot print. Haven't tested edocrab much though ...out of app memory atm.

I tried edocrab on my storm.. kept crashing and rebooting when I ran it (on startup, I never even got to try to read a barcode).. ended up removing it.. I would love to see if they release a working version soon.
